' T all whom it may concern:

Be it known that I, WILLIAM C. DILLON,

a citizen of the United States, residing at Fort Dodge, in the county of Vebster and State of Iowa, have invented certain new and useful Improvements in Auxiliary Looks for Vault Lock Mechanism, of which the following is av specification.

This invention relates to safe andvault locks, and the primary object of the invention is to provide a device for engaging a vault or safe lock bolt mechanism, when the combination lock has been forced inwardly, so as to prevent the operation of the bolts and opening-of the door.

The most common methods employed by burglars of safes and vaults are to blow the combination lock inwardly by explosives,-or to punch the lock in by knocking off the knob anddriving in the spindle, or by pulling out the pin which is attached to the knob and punchingoif thelock, or by drilling ahole through the door and punching off the lock Any onset the above methods permits the sliding of the bolt mechanism, and another objectiof the invention isto provide an improved means for effectively preventing the sliding back of the locking means if any one of these methods are employed. A- further objectof'the invention is to provide an improved device embodying a block adapted to be moved into the path of the bolt mechanism, whenthe combination lock has been tampered with byunauthorized' persons, thereby absolutely holding the bolt lock mechanism in operative position against movement. p 1 I j .1- A further objectof the invention is to pro 'vide an improvedmeans for operating the block so as tomove the same into the path of the bolt lock mechanism when the combination lock has'been forced. s

. A-further'objcct ofthe invention is to provide'means for preventingthe' severing of the connection'between the block and combination lock by the boring of hole in the safe door adjacent to the combination lock and cutting and filing the connection, thereby making the device positively burglar- A still further objectof the invention is to provide an improved auxiliary locking device for the bolt lock mechanism of a vault or safe door, when the combination lock has been rendered inoperative, of the above character which is durable andefiicientin Specifica tion of Letters Patent,

use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

Other objects of the invention will appear in the following detailed description taken in connectionwith the drawings, forming a part of thi s'specification, in which drawings': Q I

'.Figure l is a fragmentary rear elevation of 'a vault door and frame, showing the improved auxiliary locking device applied thereto. I I

Figure 2 is a fragmentary enlarged end elevation of the improved device showing the'same in applied position, and

Figure 3is anelevation of the improved device showing the same applied to a vault door. y Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the improved auxiliary locking device for thevault door'B, having the bolt lock mechanism C whichis adapted to engage the door frame and the combination lock E.

The door B, the frame D, the vault lock mechanism (3, and the combination lock E is oneof the ordinary orany preferred construction and the vault door B includes the body 5 having the usual inwardly extending flange 6 which is arranged adjacent to and parallel "with the usual flange 7 carried'by the door frame D.

The bolt lockmechanism C includes the usual bolts 8 connected by the vertically extending'bar 9 by suitable bolts 10 or other fastening elements. The bar 9 is provided wit-h the inwardly extending arm 11, which is disposed in the path of thecombination lock mechanism Ewhich prevents the sliding thereof when the combination has been set. r The improved relocking device A for the bolt mechanism 0 includes a rod 12 which is adapted to be inserted through asuitable f opening formed in the flange 6. The opening in the fiangeb may be drilled at desired placeyso that the rod 12 can placed at different or vaults and thereby render the finding of the same by a burglar. impossible. The ter- :minals of the rod 12' are threaded'as at 13 and let and the threaded end 13 is adapted to be inserted through the opening formed in the flange or ledge 6 and the same is held points on different safes ny i g l v I 1,410,800

.ja'cent to. the rear end in place by suitable lock nuts 15 and16,

which are threaded on the threaded end 13 of'the bolt into frictional engagement with the opposite facesof the flange 6. The rod 12 extends inwardly rectly in rear of theconnecting bar 9 of of projects beyond theinner edge of-the connecting bar 9. The threaded terminal 14 has qmounted thereon the solid block 17, which has one face thereof flattened as at 18, and when the face 18 is arranged in parallel relation to the bar 9, which is the normal position thereof, the free sliding movement of the bar 9 is permitted, but when the-block is turned on the rod 12 so that the face 18 lies at an angle to the bar 9, the

. block extends in the pathof thebar 9, and

prevents movement thereof. To hold the block 17 on the threaded end 14 against accidental movement, a lock nut 19 is provided for frictionally engagingthe inner'surface thereof, and-if so desired, a suitable lock washer 2O mayv be-employed and between the lock nut 19 and the block 17 for holding the same against accidental rotation. The block 17 is provided with an opening 21 adjacent to the periphery thereof, and; theyopening is directly on the, opposite'side of'the rod 12 from the flat face 18. A flexible wire or cord connector '22 has itsupper terminalinserted in the opening '21- andzknotted as at.28. Theconnector "22 is then'brought downwardly and secured to the combination lock mechanism B or anchored in such a manner tothe door thattheblock will be rotated against the tension of thespring washer, when the combination The rotation of the block 17 will move-the flattened face 18 thereof at an angle to the bar 9 and 'thereby bring the' block into the path of the bar 9 and prevent movement of's'aid bar. I 'As clearly shown in Figure 1- ofthed'rawings,=the methodv of anchoring the'lowerend of the connector 22 to the door B consists of extending. the connector .22 across the "combination'lock E and securing thesame t directly below and adof' the combination lock mechanism E. Thus it will be seen that when the combination lock is moved inwardly the {wire will be pulled, whichwill rotate the block 17. f

it To prevent the severing of the connection 22by -a'fburglar boring "a" hole adjacent to the combination lock and. inserting a tool therein and cutting orfiling the connector,

an eye 25 arranged a -cylindrical protector 24: is rotatably mounted on; the'connector'22, between the rod #12'and-the combination lock E. Ifa tool is placed against'the protector, the same'will rotate. and thereby prevent the cutting or --filing of the connector. After the combination lock has been destroyed and arranged cluding the block 17 rotated, the force of the blowing in of the lockwill break the connector and the protector 24 will slide off of the same. Owing to the fact that the connector "from "the flange 6 dij fora burglar to the bolts and the threaded terminal'14'therehasbeen blown off. The position of the rod 22 is flexible or bendable, it is impossible push up on the. connector to turn the'block after the combination lock 12 and the block 17 is made known to the owner of the safe or vault by. exactmeasurements, and in case-the block17 has been operated by burglars trying to open the safe, the owner of the safe or vault can have a hole drilled in the front side of the door at a point at right angles to the center of the flat side 18 of the block .17 and a blunt tool can'thenbe inserted through the'hole in the door and pushedagainst the peripheral notches 26 until the block 17 hasbeen turned a sufiicient distance to position the face 18 in parallelrelation with the attaching bar 9; To facilitate the returning of the block 17 to its normal position, an inwardly extending opening271s the operator can then tell'that the fa'ceu18 I is in parallel relation to thebar 9. i

From the foregoing be seen that an. improvedlocking means is provided for thevault locking mechanism of a vault or safe door which will absolutely preventilmovement of the bolt lock mechanism when :the combination lock hasbeen destroyed.
